Mirrors Automatic Dimming Rearview Mirror The vehicle has an automatic dimming inside rearview mirror with a compass display. Automatic dimming reduces the glare of lights from behind the vehicle. The dimming feature comes on and the indicator light illuminates each time the vehicle is started. Compass Compass Operation Press O or AUTO 3 , depending on the vehicle, to turn the compass on or off. When the ignition and the compass feature are on, after a few seconds, the mirror will display the compass heading. The compass automatically calibrates as the vehicle is driven. O (On/Off): Press and hold O for about three seconds to turn the dimming feature and compass display on or off. AUTO 3 (Vehicles with Intellibeam™): Press and hold for approximately three seconds to turn the compass display on or off. See Exterior Lamps on page 4-25 for more information. Compass Calibration If after a few seconds, the display does not show the correct direction, (for example, N for North), there may be a strong magnetic field interfering with the compass. Interference can be caused by a magnetic antenna mount, magnetic note pad holder or a similar magnetic item. The compass can be placed in calibration mode manually by pressing and holding O or AUTO 3 , depending on the vehicle, until a C is shown in the compass display. The compass can be calibrated by driving the vehicle in circles at 5 mph (8 km/h) or less until the display reads a direction. Cleaning the Mirror Do not spray glass cleaner directly on the mirror. Use a soft towel dampened with water. 3-36
